Products

• ProxySG Software - SGOS

Issue/Introduction

What is the recommended value of concurrent ICAP connections to be configured on a Edge SWG (ProxySG) appliance?

What is the maximum amount of ICAP connections supported on the available Content Analysis models?

Cause

The ICAP settings in the Edge SWG (ProxySG) Management Console includes an option called Sense Settings. This option will always return the same value of 250 maximum number of ICAP connections.
This value may be too high for some models of Content Analysis, and can result in queued connections and potential instability.

Resolution

Refer to this table to define the number of ICAP connections based on the model of Content Analysis you are running.
